A more thorough explanation:

Definition: Essoin day was a term used in English law to refer to the first general return day of the term, when the courts sat to receive essoins. Essoins were excuses given by a party for not appearing in court on a particular day. By the Law Terms Act of 1830, essoin days were eliminated as a part of the term.

Example: In the past, if a party was unable to appear in court on a particular day, they could give an essoin as an excuse. The court would then set a new date for the hearing, which was usually the essoin day. This allowed the party to have more time to prepare their case or to attend to other matters.

Explanation: Essoin day was an important part of the legal system in England in the past. It allowed parties to have more time to prepare their case or to attend to other matters. However, with the Law Terms Act of 1830, essoin days were eliminated as a part of the term, and parties were required to appear in court on the specified date.
